margin of the inferior claspers, but projecting laterally beyond the claspers on 
both sides. Sclerites of the juxta or penis-sheath (/) branched near the anterior 
third. Harpes divided into four pointed processes, the basal pair being widely 
separated and attached to a semi-circular and narrow sclerite ; the distal pair 
are united to a solid and somewhat rectangular process, the stem of which is 
attached to the semi-circular sclerite which supports the first pair of pointed 
appendages ; collectively these appendages are distinctly antler-like and strikingly 
characteristic.
